Can a Lift and Rotate Mechanism Handle Heavy Duty Machining Needs?

AI Thread Summary
A CNC machining fixture design is needed that can lift, rotate 120 degrees, and then lower over guide pins, specifically for heavy-duty machining with a lifting capacity of 15-20 tons. Suggestions include looking into rotary CNC tables that incorporate a lifting mechanism. The discussion also mentions exploring plug valves that utilize both linear and rotary motion. Additionally, researching patents related to cylindrical cam mechanisms may provide useful insights. The focus is on finding existing designs or manufacturers that can meet these specifications.

Hi all

I need a bit of inspiration for a new CNC machining Fixture design. First the top of the fixture must be raised to get free of the guide pins, and then the top must rotate 120 degrees before it must be lowered over the guide pin again.
I was looking for something like a rotary CNC table, but which is raised before rotation.

Can anybody help me?

Examples of where this principle is used, some drawings, or even some manufactures of a similar product.

Thanks for your help

You need to tell what is the size of the fixture you are designing.You might be interested in Plug valves where the plug has a linear motion followed by rotary motion.I suggest you to search for some patents which use a cylindrical cam mechanism.
 
Hi again

The fixture must have a lifting capacity of 15 - 20 ton.

It's for heavy duty machining.
 

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...
